Definitions

• the invention concerns a Dicycle and the like with chain transmission, multiple gears and pedals placed on the outside of the rear wheel which : -improves the functioning of the cyclist's organs and consequently energy output; -makes a vehicle with efficient mechanical and aerodynamic characteristics and, last but not least, a vehicle nice to look at.
• the venicle has been conceived by the conviction that the driver' s sitting position, typical on the traditional bicycle, does not anatomically present an optimum functioning of all those organs which work in order to get a maximum output.
• the advantages of the velocipede I conceived are the following : with this new bicycle the posterior thigh muscles (Femoral Biceps, M. Half- tendinous, M. Half-membranous, M.Psoas and partly the long adductor), working without gravitational effort, turn the energy wasted to lift the gravitational weight of limbs during the pedalling phase into energy of traction. In addition to that, all those leg muscles, which were totally unused with the traditional bicycle, play a considerable role in respect to this new velocipede.
• the innovation was born from the willingness to create a velocipede with high qualitative standards where the driver would be in a condition of maximum physical efficiency and where he could take the best aerodynamic position. It was necessary to find a way of supportmq the cyclist's mass without compromising the stability of the vehicle and the functioning of cardiac- circulation and breathing. The following solutions were found.
• the first thing to consider was the driver's position ; it had to be changeable and as comfortable as possible in order not to tire out the cyclist ( any position even the most comfortable one can't be kept for long ) .
• the position is confined: the trunk must be stretched out and the limbs stretched backwards.
• a fastening with a rapid unhooking 12 fastens the "Balancer" to the velocipede ; the special track suit, into which can be vulcanised the balancing apparatus, harmonises these structures.
• the balancer is made of material which efficaciously supports the driver's body and is flexible, light and practical (it can be made of different materials such as fiberglass and other flexible materials or compressed air pumped into tubular structures which are part of the track suit) ; it is positioned on the back of the driver Fig. 2.
• the different semirigid materials work from the gluteus region to shoulders comfortably supporting the driver ; the structure allows a stable and comfortable driving in any given position, the balancer runs on a special guide going from 80 cm. to 120 cm. (13). Even in the most aerodynamic position, when the bust is more or less parallel to the ground, the effect of the track suit, with i ts flexible traction (shoulder-saddle) and concerning supports (-the upper part of the bust mainly supported by the axillary region; - the lower part of bust mainly supported by gluteus and hips), preventing the body from falling down allow to support the body in the best way and free the arms without compromising vehicle stability.
• the supporting points of the driver are: - legs on pedals 15; - thighs and gluteus on the anatomical new saddle 11; - thorax and shoulders on the track suit with axillary supporting 8 or a corset with anatomical shoulder pads; - arms and forearms on handlebar 23.
• the means of transport turned out to be light, stable and easy to drive without compromising the driver's position and the output of energy. Its characteristics are certainly very interesting.
• the velocipede is extremely original, light ana fast. Stability is assured by the position of pedals Fig. 3, situated close to the perpendicular line 21 to the ground, passing through the hub 2 of the rear wheel 4 which prevents the bicycle from swaying even when pedalling vigorously.
• the position of the pedal unit which creates a ground-hub block, guarantees the stability of the bicycle.
• the contact of the rear wheel with the ground is not a point of fulcrum but a point of resistance towards pedals swaying and bicycle's direction changes, preventing oscillations during the pedalling phase to be transmitted to the wneels.
• the invention originates from the intuition of the new position of pedals Fig. 1 , the axes of the central movement 1 of the pedal unit is always placed on the outside of the rear wheel in a variable angle, within the area bounded by points A and B Fig.3.
• Points A and B are identified as follows: starting from the Cartesian Axes (abscissa and ordinate) having the hub of the rear wheel as an origin we divide this wheel into four equal quadrants (two lower quadrants and two upper quadrants or two external quadrants and two internal quadrants) .
• the upper quadrants correspond to the upper 180 degrees of the rear wheel without any direct connection to the ground.
• the lower quadrants correspond to the lower 180 degrees of the rear wheel with direct connection to the ground.
• the external quadrants correspond to the outer 180 degrees of the rear wheel without any connection to all the remaining parts of this vehicle.
• the internal ones correspond to the inner 180 degrees of the rear wheel with direct connection to all the remaining parts of this vehicle.
• Point A is placed on the external circumference of the rear wheel and we get it by subdividing the lower external quadrant into two equal parts with a straight line passing through the hub.
• Point B is placed on the external circumference of the rear wheel and we get it by subdividing the upper internal quadrant into two equal parts with a straight line passing through the hub. All the mechanical aspects will present a ⁇ vantages due to the position of pedals Fig. 3 and of the driver Fig. 1. I assure an advantageous reduction of weight ; since the wheelbase (distance between points 2 and 3) is more or less unchanged compared to tne traditional vehicle, the reduction of weight in this new bicycle is mainly due to the shorter diameter of both wheels and consequently of the whole vehicle. The compactness of the whole mechanism of transmission contributes to weight reduction.
• this bicycle needs a very small free gear wheel 15 ( a eight/nine cogs wheel when you get into short gears and a twenty-eight/nineteen cogs wheel when you get into long ones ) to develop a proper length in metres; even the chain 6 is shorter and this is an additional advantage for the weight of the rotating parts.
• a very small free gear wheel 15 a eight/nine cogs wheel when you get into short gears and a twenty-eight/nineteen cogs wheel when you get into long ones .
• the balancing apparatus Fig. 2 is definitely efficient and allows a comfortable and solid driving position.
• the bicycle is light, stable, easy to drive, has a very good roadholding quality.
